fix(runtime): scope mirrored-editor close intent to its runtime environment

#9804 added a leading `environmentId` parameter to recordWebSessionCloseIntent
(and isWebSessionCloseIntentPending) and updated the web-runtime-session.ts
callers, but missed the second caller in close-mirrored-editor-tab.ts, which
still passed 3 args. This broke the web typecheck on main and, had it compiled,
would have recorded the close intent under the wrong scope key
(closeIntentScopeKey(environmentId, worktreeId)) — so the host snapshot could
flash the just-closed mirrored tab back.

Pass the already-validated runtimeEnvironmentId (the same value handed to
closeWebRuntimeSessionTab immediately below) so the intent is scoped correctly.
Update the test's isWebSessionCloseIntentPending assertion to the 4-arg form.
